Summary Descriptions of Environmental Data Sets
Data are generally available for the following parameters and dates.
Other gaps exist during periods of sensor calibration, maintenance,
and repair or system upgrades.
For information regarding data sets and usage guidelines please see BOON Data Usage
Air Temperature (degrees C)
| 04/15/1988 to 03/31/2001: |
20-minute means (1 measurement per sec) |
| 02/05/2001 to present: |
Every 10 seconds |
Barometric Pressure (in Hg)
| 04/20/1988 to 03/31/2001: |
20-minute means (1 measurement per sec) |
| 06/18/2001 to present: |
Every 10 seconds |
Relative Humidity (percent)
| 05/02/1988 to 03/31/2001: |
20-minute means (1 measurement per sec) |
| 02/05/2001 to present: |
Every 10 seconds |
Ocean Surface Currents (HF Radar)
| 05/02/2001 to present date: |
Hourly, unprocessed, total vector files: these are ascii text. For smaller data requests we can reprocess raw data into total vector files and produce a snapshot (jpg) of surface current. Data must be reprocessed to produce the jpgs featured here, we do not archive these data. |
Wave Height (HF Radar)
| 12/2006 to present date: |
Unprocessed, ASCII text, in one month archives.
|
Photosynthetically-Active Radiation (micromoles per meter squared per sec)
| 02/05/2001 to present: |
Every 10 seconds |
Rain (inches)
| 12/1967 to 1992: |
Daily |
| 1992 to 2003: |
Every 10 seconds |
Seawater Salinity and Conductivity
(parts per thousand, Siemens per meter)
| 04/15/1988 to 04/02/1999: |
20-minute means (1 measurement per sec) |
| 01/01/2001 to present: |
Every 10 seconds |
Seawater Temperature (degrees C)
| 04/15/1988 to 08/31/2000: |
20-minute means (1 measurement per sec) |
| 09/01/2000 to present: |
Every 10 seconds |
Solar Radiation (watts per meter squared)
| 04/15/1988 to 03/31/2001: |
20-minute means (1 measurement per sec) |
| 02/05/2001 to present: |
Every 10 seconds |
Tide Height (meters above mean lower low water)
| 04/15/1988 to 11/29/93: |
20-minute means (1 measurement per sec) |
Wave Parameters (height in meters, period in seconds)
| 04/15/1988 to 11/29/93: |
20-minute means (1 measurement per sec) |
Wind Speed and Direction (mph, degrees from true north)
| 04/15/1988 to 03/31/2001: |
20-minute means (1 measurement per sec) |
| 05/01/2001 to present: |
Every 10 seconds |
Other Measurements-
Waves and Subsurface Ocean Currents
Acoustic Doppler Current Profiler
S4 Wave and Current Meter
Measurements of air and seawater temperature, rainfall, and barometric pressure were recorded once per day (weekdays) dating back as far as 1967 in some cases, please contact bmldata@ucdavis.edu for further information.
